An interesting hypothesis I read about focused on the era of the universe when everything was lukewarm. Literally an entire universe in the "sweet spot" for the building blocks of life to form and propagate.

The idea is that the molecules would form, and then once the universe cooled further would freeze and be spread literally everywhere in similar asteroids. The rare part would be a location sufficiently stable in the goldilocks zone to evolve advanced life, not life itself.

And that we should probably stfu instead of, you know, shooting golden maps to our planet out of the solar system.

edit: you fools
